I'm experiencing an intermittent problem with the output on an ad9389b.  Sometimes on some monitors at 1080p the video on the monitor will shake.  Also the video will periodically go black for a few seconds.  This only happens on some monitors.  We are enabling the DE signal generation on the ad9389b.  We are using RGB 444 without embedded syncs.  Our register writes are as follows:
